Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, a plurality of loading spaces 10a are provided in the upper, lower, left, and right within the housing of the medicine dispensing device 10 of this embodiment, and the medicine storage cassette 1 is loaded in each of the loading spaces 10a. Has been. The medicine storage cassette 1 is provided so as to be able to be taken in and out in the depth direction. The movable unit 11 of the medicine dispensing device 10 is provided so as to be movable in the vertical direction and the left-right direction on the front surface side (medicine dispensing side) of the medicine storage cassette 1. The movable unit 11 is provided with a weight measuring unit 12, a beam member driving unit 15, a dispensing device (not shown), a cassette operation unit, and the like. The medicine dispensing apparatus 10 is provided with a display 13 and an input unit 14.

  The drug storage cassette 1 stores, for example, a plurality of PTP sheets 100 arranged side by side in a standing state so that the pocket-forming surface faces a single direction in an upright state. An urging device for urging the PTP sheet 100 toward the front side of the medicine containing cassette 1 is provided on the back side of the cassette 1, and a dispensing slit is formed on the bottom side of the front wall portion. . When such a medicine storage cassette 1 is used, the dispensing device has, for example, an extruding member, and is configured to push the PTP sheet 100 in the foremost position downward from the slit by the extruding member.

  Alternatively, the medicine storage cassette 1 may store, for example, a plurality of PTP sheets 100 stacked in the vertical direction so that the surface on the pocket forming side faces downward or upward in the laid state. When such a medicine storage cassette 1 is used, the dispensing device has, for example, an adsorption head, and the adsorption head lifts the PTP sheet 100 located on the top of the medicine accommodation cassette 1 and dispenses it out of the cassette. Configured as follows.

  Of course, the medicine storage cassette 1 is not limited to the above structure, and various configurations can be adopted in the dispensing device.

  Said cassette operation part is comprised so that it may have an electromagnet in a front-end | tip part, and may be magnetically joined to the front magnetic part of the said chemical | medical agent accommodation cassette 1, and the said chemical | medical agent accommodation cassette 1 is taken in / out.

  As shown in FIG. 3, a cassette contact portion 12b is provided at the distal end portion of the beam member (support member) 12a in the weight measuring portion 12. The cassette contact portion 12b supports the drug storage cassette 1 so as to be lifted by contacting the upper end and the lower end of the front wall portion of the drug storage cassette 1. The base end portion of the beam member 12 a is connected to a beam member driving unit 15 provided in the movable unit 11. The beam member driving unit 15 moves the beam member 12a forward and backward to bring the cassette contact portion 12b closer to or away from the drug containing cassette 1, and lifts the drug containing cassette 1 by the cassette contact portion 12b. The beam member 12a is moved up and down to move it down or down. The mechanism for performing the advance / retreat operation includes, for example, a rack to which the beam member 12a is fixed, a pinion that moves the rack, and a motor that rotates the pinion. The mechanism for raising and lowering the beam member 12a includes, for example, a nut block to which the mechanism for performing the advance / retreat operation is fixed, a feed screw for raising and lowering the nut block, and a motor for rotating the feed screw.

  Instead of moving the beam member 12a up and down by the beam member driving unit 15, the movable unit 11 may move up and down to lift or lower the medicine storage cassette 1. Moreover, it is also possible to employ a configuration in which the base end portion of the beam member 12a is fixed to the movable unit 11 (not advanced or retracted) without including the beam member driving unit 15. In the case of such a configuration, the medicine storage cassette 1 is pulled out by the cassette operating portion used for the medicine dispensing, and the front wall portion of the medicine storage cassette 1 is engaged with the cassette contact portion 12b by this drawing operation. Can be made. When measuring the weight of the medicine storage cassette 1, the cassette operation unit is separated from the medicine storage cassette 1 so that the weight measurement of the medicine storage cassette 1 is appropriately performed.

  The beam member 12a has a material, a cross-sectional shape, and the like so that it can be bent somewhat when the medicine storage cassette 1 is lifted. And the strain gauge 12c is affixed on the upper surface, for example of the said beam member 12a. The strain gauge 12c has a property of changing electric resistance by strain (deformation). This change in electrical resistance is given to a control unit 20 described later by an electric wire (not shown), and the control unit 20 converts the electrical resistance into a weight (amount of strain). Of course, it is also possible to measure the weight using physical properties different from changes in electrical resistance due to strain (deformation).

  Here, in this embodiment, the bottom plate of the loading space 10a is not positioned on the front end side of the medicine storage cassette 1 (see FIG. 2), so that the medicine storage cassette 1 is not pulled out to the front side. However, the cassette contact portion 12b can be engaged with the front wall portion of the medicine storage cassette 1. When measuring the weight of the medicine storage cassette 1, if the whole medicine storage cassette 1 is not extracted from the loading space 10 a, the loading space 10 a has a height allowance for the lifting. (Clearance) is given, and the medicine storage cassette 1 is lifted by a distance shorter than the clearance. On the other hand, when the entire medicine storage cassette 1 is extracted from the loading space 10a and lifted, the clearance is not particularly required.

  In addition, the determination as to whether or not the medicine storage cassette 1 is completely lifted from the bottom plate of the loading space 10a and the weight of the medicine storage cassette 1 can be determined is determined by whether the medicine storage cassette 1 is in the loading space 10a. It can be performed by detecting by using an optical sensor or the like that the aircraft has completely floated from the bottom plate. Alternatively, the weight may be repeatedly calculated during the ascending operation of the beam member 12a, and the weight when the weight is regarded as a constant value may be set as the final weight. In this case, it is possible to accurately determine the weight without particularly determining the flying. It is also possible to eliminate the need for installing the optical sensor by sufficiently floating the medicine storage cassette 1 from the bottom plate of the loading space 10a.

  FIG. 4 is a block diagram showing an outline of a control system of the medicine dispensing apparatus 10. The control unit 20 includes a microcomputer, and processes information input from the input unit 13 and performs processing such as displaying the processed information on the display 14. For example, the operator uses the input unit 13 to input an initial input of which medicine sheet is stored in which medicine storage cassette 1, and the replenishment number input when the PTP sheet 100 is refilled in the medicine storage cassette 1 (This number input may be unnecessary) Prescription information input for payout can be performed.

  In addition, the control unit 20 moves the movable unit 11 to the target medicine storage cassette 1 based on the prescription information, and executes the PTP sheet 100 dispensing process. It is also possible to perform fractional payout processing of the PTP sheet 100. With regard to the mechanism for such fractional payout processing, an apparatus disclosed in Japanese Patent Application Laid-Open No. 2011-41789 can be used. The apparatus disclosed in the above publication includes a cutting member that cuts a fraction of a medicine sheet that has been gripped and conveyed by a gripping member.

  The control unit 20 moves the movable unit 11 to the front surface of the medicine storage cassette 1 when, for example, an inventory management instruction is input from the input unit 13 by an operator or when a predetermined date and time for inventory management arrives. Move sequentially to the location. In addition, for example, a sensor (optical sensor or the like) is provided in each loading space 10a, and the medicine storage cassette 1 is once removed and remounted for the user to replenish or remove the PTP sheet 100. When detected by the sensor, the control unit 20 moves the movable unit 11 to the front surface of the medicine storage cassette 1 in the detected loading space 10a. The control unit 20 moves the movable unit 11 to the location of the target medicine storage cassette 1 as described above, and then drives the beam member driving unit 15 to contact the cassette in the weight measuring unit 12. The portion 12 b is engaged with the front wall portion of the medicine storage cassette 1. Then, the control unit 20 detects the engagement (contact) by the detection unit, and then lifts the medicine storage cassette 1 by the beam member 12 a of the weight measurement unit 12. The detection unit includes, for example, a switch provided on the cassette contact unit 12b so as to be turned on when the cassette contact unit 12b comes into contact with the medicine storage cassette 1.

  In this embodiment, the drug container cassette 1 is engaged with the front wall portion of the drug container cassette 1 without pulling out the drug container cassette 1 to the front side so that the drug container cassette 1 is more than the clearance. I try to lift only a short distance. As described above, when the medicine storage cassette 1 is not pulled out at all, since the pulling-out operation is unnecessary, the time required for weight measurement can be shortened. Moreover, when the structure which does not pull out the said medicine storage cassette 1 is employ | adopted, the dimension of the depth direction (front-back direction) in the medicine delivery device 10 can be shortened.

  The control unit 20 energizes the strain gauge 12 c of the weight measuring unit 12, measures its electric resistance, and converts this electric resistance into the weight of the medicine storage cassette 1. Further, the control unit 20 reads the weight information per sheet of the PTP sheet 100 accommodated in the target medicine storage cassette 1 and the empty weight information of the target medicine storage cassette 1 from the storage unit 16.

  Then, the control unit 20 subtracts the empty weight of the medicine storage cassette 1 from the measured weight of the medicine storage cassette 1 obtained by converting the output of the weight measurement unit 12 into the medicine storage cassette 1. The total weight of the remaining PTP sheet 100 and the entire fraction is calculated. Next, the control unit 20 divides the total weight by the weight per sheet of the PTP sheet 100, and outputs a quotient (integer) and a remainder. The quotient indicates the number of PTP sheets 100, and the control unit 20 stores the calculated number in the storage unit 16 as the number of stocks of the corresponding medicine storage cassette 1.

  On the other hand, the surplus indicates the fraction remaining in the medicine storage cassette 1. In this embodiment, the remainder is rounded down without calculating the fraction using the remainder. This is because when the fraction is cut based on the prescription information, a shift occurs in the cutting position, or the remainder does not always accurately represent the fraction due to the presence or absence of the ear portion of the PTP sheet 100. . For this reason, when the fraction is paid out based on the prescription information, a theoretical inventory process is performed in which the fraction is subtracted and managed. In this embodiment, replenishment of medicine is performed in units of PTP sheets and not in units of fractions. However, if supplementation is performed in units of fractions, the supplemented fractions are added to the theoretical inventory.

  The weight information in the empty state of the medicine storage cassette 1 is stored in the storage unit 16 by measuring the weight of the medicine storage cassette 1 by the weight measuring unit 12 in an empty state in which the medicine sheet is not stored. You may do it. Such a measurement process can be performed simultaneously for all the medicine storage cassettes 1 at the shipping stage or the installation stage of the medicine dispensing apparatus 10. Moreover, it is also possible to measure the weight information in the empty state of the medicine storage cassette 1 with another weight scale without using the weight measuring unit 12. Further, the weight measurement may be performed not only in the shipment stage and the installation stage but also when the medicine storage cassette 1 is replaced.

  The above processing also shows a method for calculating the remaining amount of medicine in the medicine dispensing apparatus. That is, the method for calculating the remaining amount of medicine is the front surface of the target medicine storage cassette 1 among the plurality of medicine storage cassettes 1 loaded in the loading space 10a provided in the medicine dispensing apparatus 10. The step of moving the beam member (support member) 12a for lifting the drug storage cassette 1 using the movable unit 11 for dispensing the drug on the side, and the beam member 12a moved to the loading space 10a side Allowing the drug storage cassette 1 to be lifted, and moving the beam member 12a upward or pulling out the drug storage cassette 1 from the loading space 10a with the beam member 12a. The step of lifting the storage cassette 1 and the drug storage cassette 1 in the state where the drug storage cassette 1 is lifted. And a step of measuring a weight, a step of calculating the remaining amount of the drug of the drug accommodating cassette 1, based on the weight measured, and. Further, in this method, the control unit 20 is engaged with the front wall portion of the medicine storage cassette 1 by the cassette contact portion 12b, that is, whether the medicine storage cassette 1 can be lifted by the beam member 12a. Whether or not is detected by the detection unit.

  Further, in this embodiment, when the operator refills the medicine storage cassette 1 with the PTP sheet 100, the number of replenished sheets can be input from the numerical keys in the input unit 13 for theoretical inventory management. In addition, the inventory management is also performed by calculating the number of sheets based on the weight measured by the weight measuring unit 12 as described above so that the inventory can be verified.

  The configuration is not limited to the above. For example, a configuration in which the input of the replenishment number or the like by the input unit 13 is unnecessary can be adopted. Here, if the operator replenishes or removes the medicine sheet without inputting the replenishment number or removal number to the medicine dispensing apparatus 10, the theoretical stock and the actual stock will not match. For example, when a user who needs a predetermined medicine sheet directly takes out the medicine sheet from the medicine storage cassette, or in a pharmacy in which a plurality of medicine dispensing devices 10 are introduced, a certain medicine sheet is in stock in one device 10. When it becomes zero, the medicine sheet may be transferred from the medicine storage cassette 1 of another device 10. Even in such a case, accurate inventory management can be performed by calculating the number of sheets based on the weight measured by the weight measuring unit 12.

  Further, as the medicine storage cassette 1, a medicine storage cassette 1A shown in FIGS. 5 and 6 can be used. This medicine storage cassette 1A has a plurality of storage areas A in the depth direction, and has a function of advancing the PTP sheet 100 in the rear storage area A when the PTP sheet 100 in the front storage area A disappears.

  Specifically, in the upper case portion 2 of the medicine storage cassette 1A, this depth direction is formed so that a plurality of four storage areas A that can be stored in a stacked state or in a packaged state are formed in the depth direction. A plurality of partition members 3 are located at intervals. And in this embodiment, the said storage area | region A is formed so that the said PTP sheet 100 or a package may be accommodated in the state which turned the transversal direction to the said depth direction. That is, the horizontal direction of the accommodation area A is longer than the depth direction.

  Among the four storage areas A, the frontmost storage area A is provided with a pressing portion 9 that sandwiches the PTP sheet 100 from the side and prevents the stacking deviation. The pressing portion 9 is elastically supported by a leaf spring 9a and presses the PTP sheet 100 from the side. In addition, moving members 4 are provided on the right and left sides of the upper case portion 2. The moving member 4 can move the accommodating area A in the depth direction (back side and near side) by moving the plurality of partition members 3 simultaneously, and the accommodating area when moving to the near side. The PTP sheet 100 or the package in A can be moved to the near side.

  The partition member 3 is separated in a direction (left-right direction) intersecting with the depth direction to form a pair, and the partition member 3 forming the pair is a PTP sheet 100 accommodated in the accommodation area A or a package body. It is located so as to engage with the corners on one side. Each moving member 4 has a plurality of locking holes 4a formed at predetermined intervals in the depth direction. Thereby, the partition member 3 can be detachably attached to the locking hole 4a, and the depth direction interval (accommodating region) of the partition member 3 can be changed by changing the locking hole 4a to be used. It is possible to change the size of A).

The distal end of the guide pin 4d enters a guide groove 7a formed in the guide plate 7, and the distal end surface of the guide pin support portion 4c is in contact with the upper surface of the bank portion of the guide groove 7a.

  FIG. 9 is a perspective view showing the medicine storage cassette 1A in a state where the upper case portion 2, the slide side plate 55, and the moving member 4 are removed. The guide groove 7a of the guide plate 7 is formed in a parallelogram shape having two inner and outer guide groove portions extending in parallel with the depth direction and two folded groove portions connecting them.

  When the guide pin 4d is positioned in the inner guide groove and the moving member 4 moves closer to each other, the partition member 3 is placed at the corner of the PTP sheet 100 accommodated in the accommodating area A. The engagement becomes possible, and the PTP sheet 100 in each region A can be moved to the near side by the near side movement. On the other hand, when the guide pin 4d is positioned in the outer guide groove and the moving member 4 moves away from each other, the partition member 3 is a corner of the PTP sheet 100 accommodated in the accommodating area A.
